Would recommend either the Pearson's Pond (
www.pearsonspond.com) or Alaska's Capital Inn B&Bs. My folks stayed at the Goldbelt and found it to be perfectly fine. You might also check out the Driftwood Lodge (
www.driftwoodalaska.com)- they will pick you up from the airport and will loan you bikes.
Have heard good things about Extended Stay America (formerly Aspen) right next to the airport.
Feel free to PM if you have any questions.
